In this paper we present a new image denoising filter that can suppress additive noise components while preserving signal components in the wavelet domain. The proposed filter, which we call an adaptive wavelet shrinkage(AWS) filter, is composed of two operators: the wavelet killing operator and the adaptive shrinkage operator. Each operator is selected based on the threshold value which is estimated adaptively by using the local statistics of the wavelet coefficients. In the wavelet killing operation, the small wavelet coefficients below the threshold value are replaced by zero to suppress noise components in the wavelet domain. The adaptive shrinkage operator attenuates noise components from the wavelet components above the threshold value adaptively. The experimental results show that the proposed filter is more effective than the other methods in preserving signal components while suppressing noise.

Spatial image processing software requires various user interactions to make a plan, prepare necessary data such as images, vectors, ancillary data and user-defined data, execute functions according to pre-defined procedures, analyze and store the results. In this manner, overall processes are controlled by user interactions. In this paper, we propose visual modeler which has the automated spatial image processing technique to minimize user interactions and re -use repeatable procedure. The proposed visual modeler is designed to use inter-operable components proposed by OpenGIS consortium as well as conventional COM components.

In this paper we propose a novel way to restore degraded image using wavelet transform & filterbank. First, we devide a degraded image into 4-suband images using UDWT(Undecimated Wavelet Transform), and then use a proper CLS (Constrained Least Square) filter in each subband. Using a proper CLS filter ineach subband, we can save high grequency components of original image. We reconstruct a restored image from the downsampled subband images using wavelet tansform. Even though there is a trade-off between ISNR and calculation loads, we reduce the calculation loads by using wavelet transform in reconstruction with a negligible degradatiion in ISNR.

Recently, studies of image analysis, as the preprocessing stage for medical image analysis or image retrieval, are actively carried out. This paper intends to propose a way of utilizing color components for image retrieval. For image retrieval, it is based on color components, and for analysis of color, CLCM (Color Level Co-occurrence Matrix) and statistical techniques are used. CLCM proposed in this paper is to project color components on 3D space through geometric rotate transform and then, to interpret distribution that is made from the spatial relationship. CLCM is 2D histogram that is made in color model, which is created through geometric rotate transform of a color model. In order to analyze it, a statistical technique is used. Like CLCM, GLCM (Gray Level Co-occurrence Matrix)[1] and Invariant Moment [2,3] use 2D distribution chart, which use basic statistical techniques in order to interpret 2D data. However, even though GLCM and Invariant Moment are optimized in each domain, it is impossible to perfectly interpret irregular data available on the spatial coordinates. That is, GLCM and Invariant Moment use only the basic statistical techniques so reliability of the extracted features is low. In order to interpret the spatial relationship and weight of data, this study has used Principal Component Analysis [4,5] that is used in multivariate statistics. In order to increase accuracy of data, it has proposed a way to project color components on 3D space, to rotate it and then, to extract features of data from all angles.

This purpose of this study is to analyze the pursuit of current fashion trends and fashion image types of middle-aged women in Korea. This study attempted to investigate the standards and properties of these different types of fashion images. The overall characteristics of middle-aged women and the concepts of personal image and fashion image were investigated through literature research. Survey and analysis based on Q methodology was conducted. Factors of personal image, fashion image and components of fashion image were analyzed by collecting information from in-depth workshops and focus group interview of an expert group. The results of this study are as follows: 1) The main factors influencing the current fashion image of women in their forties and fifties in Korea are classified into six types. 2) The elements of fashion image that Korean women in their 40s and 50s pursue are divide into four types. 3) Each type can be recognized by specific fashion image components and colors. 4) This shows that middle-aged Korean women are highly conscious of how others perceive them and have a desire to not stand out from others. It also shows that they are very active in pursuing fashion and following trends, which is the image of an active and dignified woman. This study provides the framework that enables sorting of the fashion images types that middle-aged Korean women want to pursue. The results from analyzing the factors can be used to recognize specific fashion images, and can be used in the planning and designing of fashion items for middle-aged Korean women.

Purpose - This study aims to establish the relationships among brand equity, brand attitudes, and Visual Merchandising (VMD) in bakery stores. The results will help bakery franchisees and franchisers in devising appropriate strategies for successfully managing their bakery shops. Research design, data, and methodology - The VMD model for bakery shops comprises harmony, attractiveness, suitability, pandemic, functionality, and reliability. Further, brand equity encompasses brand awareness, perceived quality, and brand image. In this study, the VMD factors of bakery shops are used as independent variables, while brand equity and brand attitude are used as dependent variables. This study aims to ascertain the extent of the influence VMD components of bakery shops have on brand equity and brand attitude. Regression analysis was used to verify those effects. The measurement items, deemed reliable and valid in a previous study, were modified for this study. Questionnaires were distributed to 500 consumers nationwide, of whom 340 were used for the sample. The SPSS 19.0 statistical program was used for the analysis. Results - First, among the VMD bakery shop components, harmony, attractiveness, and pandemic have a positive impact on brand equity (brand awareness and brand image). Second, amongst the VMD components of bakery shops, attractiveness, pandemic, and reliability have a positive impact on brand equity (perceived quality). Third, amongst the VMD components of bakery shops, harmony, attractiveness, and reliability have a positive impact on brand attitude. Fourth, brand equity (brand awareness, brand image, and perceived quality) have a positive effect on brand attitude. Conclusions - This study identifies the relationships between the VMD components of a bakery shop and brand equity and attitude in order to propose a new model. The study has several practical implications. First, the development of brand equity and management can be important components in bakery shops' determination of whether their VMD components have an impact on brand equity. Second, among VMD components, harmony and attractiveness have a positive influence on the choice of bakery shop, while reliability and pandemic have a partly positive influence on the choice of bakery shop. Therefore, store atmospheres should be attractively designed, and store menus and interiors should be reviewed periodically to conform to the latest trends. This study suggests marketing strategies for brand equity formation. First, providing collateral product quality, hygiene, and safety benefits as well as product offerings to complement the season and employees' services should be considered. Second, display methods, illumination designs, and new product ideas should be periodically reviewed. Third, these should complement the overall harmony of the interior and exterior and of the store atmosphere in order to be attractive. Funds should thus be dedicated specifically for the facilities and their interiors. Fourth, it is necessary to build a friendly and relaxed image that can be easily called to mind by the customers.

The image retrieval generally shows the same or similar images to a query image as a result. In the case of rotated image, however, its performance tends to be debased significantly. We propose a method to ensure a reliable image retrieval of rotated images as follows; First, to obtain feature points of query/DB images by Harris Corner Detector; and then, utilizing the feature points, to find the object's axis and query/DB images into rotation invariant images with Principal Components Analysis algorithm. We have experimented with 6,000 natural images which are 256 pixels in diameter. They are 1,000 Wang's images and their rotated images by $30^{\circ}$, $45^{\circ}$, $90^{\circ}$, $135^{\circ}$ and $180^{\circ}$. The simulation results show that the proposed method retrieves rotated images more effectively than the conventional method.
